Creer une marketplace thématique

Preference for : French (or english) speaking freelancer, good first relationship (detailed answer, technology used, clear planning, ...), popular CMS and plugins, and minimum custom development. Mainly based on a standard CMS/Framework (including plugins), the developer has to create a full responsive travel marketplace for desktop & web-mobile. The app is a kind of pinterest-like application enabling to browse a Travel Product Catalogue, then click to Vendor website for booking the product. Individual products are hotels, packages, activities...sold by Vendors. No payment is made on the marketplace. The platform has to be designed to accept more than 1 million products. Developer has to develop from scratch the app, and interface it with the Product Catalog Database he will also build the structure. The front end design has to be quite simple and no templating will be provided (except the 2/3 main screens in powerpoint provided). End-user process : - The end user opens the app and can search Products by Destination (via mainmenu) or by searching in searchbox - The user can browse listing of Products corresponding to the selected destinations (and filter it by category or tag). Products have each one large photo, a Title, a Destination, a Price, a Vendor Url, description text, Vendor Name and additional Categories and tags....not all these product fields are mandatory - If the user selects « More Info button», a pop-up is displayed with the additional Text Description on the Product and he can click to the Merchant selling the product. Clicks have to be registered properly for invoicing the Vendor Deliverable : turnkey platform installed on our own server (based in France), including front office, databases structure and iframe for encapsulating in another website. Use most common and opened CMS / Framework / API / Tools, easy extract of click stats, no technical support from me. Preference for open e-commerce CMS that provides plenty of plugins Speed requirement : very speed website (test it with >1 000 000 products), cache management with a popular plugin Developer needs to have already developed a similar app and has to send me the urls where i can check the apps he has developed from scratch, alone Environment : Hosting on OVH server (france), regular back-ups, no maintenance shall be required on the project and during the life cycle of the website Detailed specs will be provided
